Abstract: 23,765. Riesebeck, K. Oct. 19, 1912, [Convention date]. Void [Published under Sect. 91 of the Act]. Parcelling.-Relates to a machine for tying a string 1, Fig. 1, with a carrying-loop 3 around a parcel 2, and, instead of knotting the ends 4 of the string, sealing them with a mass 5 of plastic material. Two parcel-holders 10, 11, Fig. 5, are provided, the supports of which can slide along the guideway of a carrier 12 towards one another. The carrier 12 is secured at the ends of a shaft 17. Each holder consists of a box-like casing formed of two parts 20, 21, Figs. 13 and 14, pivoted together and in the ends of which vertical slots 23, 26, respectively are provided, a space 28 also being left when the two members close on the parcel 2. A string-guide is formed by two spring-controlled carriers 30, which slide in the vertical slots at the inner ends of the holder. As shown in Fig. 5, one of the holders 10 projects above the table 8 of the machine in position to receive a parcel. The holders are then moved towards the centre of the carrier 12, the shaft 17 makes a half-turn, and the holders move back along the carrier 12. Thus the position of the holders is interchanged and a parcel has been carried down to the tying- mechanism while a tied parcel is presented above the table. The tying-mechanismconsists of a tying-fork 51, Figs. 5 and 15, which is mounted on an horizontally-sliding carriage 52, and the device for forming the carrying-loop and sealing the string. The tying-fork consists of two arms 61, 62, which can be moved along a guide 64, the guide in turn being rotatable by a shaft 65. Each arm is provided with a spring clip 69, 70, and a string-tensioning device 71 which can be moved along the arm. The fork 51 moves from the position shown in Fig. 5 towards the right so that the arms 61, 62 pass through the vertical slots 23, 26 of the lower holder 11 until their ends project past the end of the holder. A string-carrier now conveys the string from the grip 70, Fig. 15, on the lower arm to the grip 69 on the upper one. The carrying-loop 3, Fig. 1, is then formed by a hook-member 107, Figs. 20 and 24, which engages the string 1 and then moves to the right, drawing the string in a loop between two pivoted tubular jaw members 110 which close on the string and press it against the parcel. The fork 51 is then moved back to the position shown in Fig. 5, thus drawing the string around the parcel in the holder 11. The carriers 30, Fig. 14, then move to the middle of the holder, thus taking the string to the centre of the parcel, and the fork is rotated by the shaft 65 through one and a quarter turns so that it comes to rest in an horizontal position. The fork is again moved to the right, the arms passing through the slot 28, Fig. 13, in the holder 11. During this movement, the string is tensioned by the tensioning-device 71: When the movement of the fork ceases, the ends of the string are gripped by the clips 120, Fig. 24, which swing about vertical pivots 119<a> and cross the ends of the string in the jaws 110 over the base of the carrying-loop. The cords are then secured by a seal of plastic material. Tubular matrix-carriers move into the jaws 110, and the upper matrix-carrier has a feeder which receives a supply of plastic material from a receptacle 140, Fig. 5, and feeds it to the matrices. The seal is then pressed and colour stamped.
